Terraform module to create and manage AWS WAFv2 rules.

> [!TIP]
> #### 👽 Use Atmos with Terraform
> Cloud Posse uses [`atmos`](https://atmos.tools) to easily orchestrate multiple environments using Terraform. 
> Works with [Github Actions](https://atmos.tools/integrations/github-actions/), [Atlantis](https://atmos.tools/integrations/atlantis), or [Spacelift](https://atmos.tools/integrations/spacelift).

## Usage

For a complete example, see [examples/complete](examples/complete).

For automated tests of the complete example using [bats](https://github.com/bats-core/bats-core) and [Terratest](https://github.com/gruntwork-io/terratest)
(which tests and deploys the example on AWS), see [test](test).

```hcl
module "label" {
  source = "cloudposse/label/null"
  # Cloud Posse recommends pinning every module to a specific version
  # version = "x.x.x"

namespace = "eg"
  stage     = "prod"
  name      = "waf"
  delimiter = "-"

tags = {
    "BusinessUnit" = "XYZ",
  }
}

module "waf" {
  source = "cloudposse/waf/aws"
  # Cloud Posse recommends pinning every module to a specific version
  # version = "x.x.x"

geo_match_statement_rules = [
    {
      name     = "rule-10"
      action   = "count"
      priority = 10

statement = {
        country_codes = ["NL", "GB"]
      }

visibility_config = {
        cloudwatch_metrics_enabled = true
        sampled_requests_enabled   = false
        metric_name                = "rule-10-metric"
      }
    },
    {
      name     = "rule-11"
      action   = "allow"
      priority = 11

statement = {
        country_codes = ["US"]
      }

visibility_config = {
        cloudwatch_metrics_enabled = true
        sampled_requests_enabled   = false
        metric_name                = "rule-11-metric"
      }
    }
  ]

context = module.label.context
}
```

> [!IMPORTANT]
> In Cloud Posse's examples, we avoid pinning modules to specific versions to prevent discrepancies between the documentation
> and the latest released versions. However, for your own projects, we strongly advise pinning each module to the exact version
> you're using. This practice ensures the stability of your infrastructure. Additionally, we recommend implementing a systematic
> approach for updating versions to avoid unexpected changes.

## Running Terraform Tests

We use [Atmos](https://atmos.tools) to streamline how Terraform tests are run. It centralizes configuration and wraps common test workflows with easy-to-use commands.

All tests are located in the [`test/`](test) folder.

Under the hood, tests are powered by Terratest together with our internal [Test Helpers](https://github.com/cloudposse/test-helpers) library, providing robust infrastructure validation.

Setup dependencies:
- Install Atmos ([installation guide](https://atmos.tools/install/))
- Install Go [1.24+ or newer](https://go.dev/doc/install)
- Install Terraform or OpenTofu

To run tests:

- Run all tests:  
  ```sh
  atmos test run
  ```
- Clean up test artifacts:  
  ```sh
  atmos test clean
  ```
- Explore additional test options:  
  ```sh
  atmos test --help
  ```
The configuration for test commands is centrally managed. To review what's being imported, see the [`atmos.yaml`](https://raw.githubusercontent.com/cloudposse/.github/refs/heads/main/.github/atmos/terraform-module.yaml) file.
